Study on behavior of male rat 3 months after electromagnetic pulse irradiation

AIM: The present paper investigated the effect on open-field behavior of male rat 3 months after electromagnetic pulse irradiation. MATERIALS AND RESULTS: Mature male rats were randomly divided into control group, loop irradiation group and 1000P irradiation group. Rats in the EMP irradiation group were exposed to EMP. The field intensity was 100KV/m with 100 pulses and 100KV/m with 1000 pulses. The changes of behavior were observed with open-field test in rats 3 months after electromagnetic pulse irradiation. Accumulative Distance (AD), Accumulative Time (AT), AD of Walking, AT of Walking, AD of Resting, AT of Resting were recorded. Analysis of open-field test indicated that the activity of the EMP irradiation group has a significant decrease compared with control group (P<0.05), And it was also indicated that there are no significantly difference between loop irradiation group and 1000P irradiation group. CONCLUSION: It is inferred that Electromagnetic pulse irradiation can cause some disorders of behavior of rats, which may induce a significant decrease in the activity in rats 3 months after EMP irradiation.
